Line is perpendicular to the axis of axis, and described adjustment screw is threadeded with adjusting sleeve, and described top spring is arranged at
In adjusting sleeve and between adjustment screw and push rod, by means of the thrust of top spring, c-type connecting shaft block pushes against
Axis.
On the basis of technique scheme, the intrados of described c-type connecting shaft block studs with friction plate, institute
State friction plate to contact with axis.
On the basis of technique scheme, described axis is connected with H jacket, described c-type connecting shaft block
Friction plate on intrados contacts with the circumferential surface of H jacket recess.
On the basis of technique scheme, the width of described H jacket recess and the width of c-type connecting shaft block
Equal.
On the basis of technique scheme, also including U-shaped support member, it is fixed in stool seat and wherein
Portion offers installing hole, and described adjusting sleeve is fixedly installed in installing hole.
This utility model has the advantage that the life-span is long, is not affected safety by temperature and the temperature difference secure,
Can adjust various different reversal rate by client's difference demand, processing is simple, easy to make, operation
Conveniently, easily safeguard, be adapted to the region of any different temperature difference, there is not gas, liquid leakage,
Will not produce any pollution, can allow that mounting does is relatively thin, more attractive in appearance, is not take up space.

Intermediary is indirectly connected to.For the ordinary skill in the art, can understand with concrete condition
Above-mentioned term concrete meaning in this utility model.
As it is shown in figure 1, a kind of mechanism for regulating turnover stool reversal rate of the present embodiment, it is special
Levy and be, including: axis 8, c-type connecting shaft block 11, push rod 21, adjusting sleeve 12, top spring 13 and tune
Whole screw 14, described axis 8 and fixing stool carry on the back 1 Joint, described adjusting sleeve 12 with can relative stool
Stool seat 5 Joint of the back of the body 1 rotation, described push rod 21 one end and c-type connecting shaft block 11 Joint, separately
One end installs in adjusting sleeve 12 and is slidably connected with adjusting sleeve 12；The axis of described push rod 21 is vertical
In the axis of axis 8, described adjustment screw 14 is threadeded with adjusting sleeve 12, and described top spring 13 sets
It is placed in adjusting sleeve 12 and is adjusting between screw 14 and push rod 21, by means of pushing away of top spring 13
Power, c-type connecting shaft block 11 pushes against axis 8.Top spring 13, top spring 13 is promoted to push away by adjusting screw 14
Dynamic c-type connecting shaft block 11, it is achieved rub between the H jacket 9 on c-type connecting shaft block 11 and axis 8 and subtract
Speed, screws advance and retreat by adjusting screw 14 in adjusting sleeve 12, the elastic force of scalable top spring 13,
And then the pressure between the friction plate 10 and H jacket 9 on regulation c-type connecting shaft block 11, it is achieved adjustable
Whole frictional force, so avoid stool the back of the body because of on turn over or under turn over speed injure the soonest user and generation noise.
This governor motion simple and stable, is hardly damaged, and is taken up space little, does not use antivibrator or gas bullet
Springs etc., have also got around axis 8 and have used the forms such as bent axle, camshaft and eccentric shaft, can be greatly reduced seat
The thickness of frame.Meeting governor motion to be all hidden in stool seat 5, one is attractive in appearance simultaneously, and two is to avoid
User is caused damage (crushing) by above-mentioned motion when action.
Preferably, the intrados of described c-type connecting shaft block 11 studs with friction plate 10, described friction plate
10 contact with axis 8.
